503 -> 132 across three parts. The seven mtk_root consumers are untouched because the path they source is unchanged. Identical 28-function set before and after, checked after each of the two carves. The `<<<` in this file are here-strings, not heredocs - worth confirming rather than assuming, after enforce_vbox_hosts.
